Hydrochloric Acid → HCID 18620158, compound

Participants

Reaction Steps

To a stirred solution of methyl 2-benzyloxy-5-vinylbenzoate (1.95 g) in methanol (10 ml) was added 2N aqueous sodium hydroxide solution (7.6 ml) at room temperature, and the mixture was heated under reflux for 1 hour with stirring. The reaction mixture was acidified with 2N hydrochloric acid, and the resulting mixture was extracted with dichloromethane. The extract was washed with brine and dried over anhydrous magnesium sulfate, and the solvent was removed under reduced pressure. Crystallization of the residue from a mixed solution of hexane and diethyl ether (2/1) gave 2-benzyloxy-5-vinylbenzoic acid (1.49 g)
